Devise Omniauth-Facebook rememberable

Problem

I have Devise Omniauth-Facebook authentication. The log in with facebook works, but the Session is lost when the user goes to localhost:3000. I have the following GEMs:

Devise 4.2.0
Rails 5
omniauth 1.4.0
omniauth-facebook 4.0.0
omniauth-oauth2 1.4.0

Description

The Session works correctly for users not authenticated with Omniauth-Facebook,

This is my devise.rb omniauth-facebook settings:

config.omniauth :facebook, "APP_ID", "APP_SECRET", callback_url: "http://127.0.0.1:3000/users/auth/facebook/callback", scope: 'public_profile, email', image_size: 'large', provider_ignores_state: true

I already tried the following solution that did not work:

turning off protect_from_forgery
OmniAuth.config.full_host = "http://127.0.0.1:3000"
Following the accepted solution of Jeroen van Dijk at the following post: Devise and OmniAuth remembering OAuth For this solution, in my rake routes I do not have the path user_oauth_connect_path, even if I added the route in routes.rb. I also think this is not the solution to my problem because I have Devise 4.2.0 and Rails 5
@user.remember_me = true

All the previous solutions were taken from the following stackoverflow discussions:

Omniauth+Facebook lost session

The code is the standard one included in the guides from github of Devise and omniauth-facebook Thanks a lot for your help Fabrizio Bertoglio

Maybe this is the solution to my problem? Facebook login right now works and If the session is not stored, the user can login back again without problems. I did not have any more experiences about losing the session so I am not taking so much interest in this issue.

Notice that Devise's RegistrationsController by default calls User.new_with_session before building a resource. This means that, if we need to copy data from session whenever a user is initialized before sign up, we just need to implement new_with_session in our model. Here is an example that copies the facebook email if available:

class User < ApplicationRecord
  def self.new_with_session(params, session)
    super.tap do |user|
      if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["raw_info"]
        user.email = data["email"] if user.email.blank?
      end
    end
  end
end

Finally, if you want to allow your users to cancel sign up with Facebook, you can redirect them to cancel_user_registration_path. This will remove all session data starting with devise. and the new_with_session hook above will no longer be called.
